JOURNAL-BOX.

Specification of Letters Patent.

Application filed July 21, 1908.

Patented Oct. 31, 1911. Serial No. 444,606.

To all whom it may concern.- I

Be it known that I, CHARLES F. MURRAY, a citizen of the United States,and a resident of Chicago, Oook county, Illinois, have invented certainnew and useful Improvements in Journal-Boxes, of which the following isa specification.

This invention relates to car truck journal boxes and has particularreference to the means for securing and operating the lid or cover forthe said box.

One of the advantages which is sought to be attained by the presentinvention is the complete inclosure of the operating springs for thejournal box lid. The main objection to the lids and operating means nowin use is the fact that they are liable to become broken or lost,because of arduous operation conditions, particularly when exposed tothe weather in any way, or when placed on the interior of the lid theirtemper is destroyed by the overheating of the box, which is liable tooccur at intervals. Another advantage sought to be obtained by myinvention is the provision of a box which shall admit of its interchangewith any M. O. B. lid. This is desirable, because lids are frequentlybroken in service and unless they can be repaired promptly mustnecessarily remain open until the terminal is reached, the journal inthe mean time collecting large amounts of dust and grit.

My invention will be more readily under stood by reference to theaccompanying drawings forming a part of this specification and in which;

Figure 1 is a front elevation partly in section; Fig. 2 is asideelevation in section on line 22 of Fig. 1; Fig. 3 is a horizontalsection on line 3-3 of Fig. 1; Fig. l is a perspective of a fragment ofthe lid showing its cam surface; Fig. 5 is a fragmentary view of thecooperating cam parts of the lid and journal box lugs; and Fig. 6 is aperspective view of the follower ring.

Referring more particularly to the drawings, A, is the journal box and Bis the lid. The journal box is provided with an upstanding lug, 6,having an aperture therein, one end, 7, of which is contracted to thesize of the bolt, the main portion, 8, is slightly enlarged and an outerportion, 9, is still further enlarged. Within the main opening, 8, Iplace a spring, 10, which is retained in place by means of a ferrule orring, 11,

which is circular in form. On the side of the upstanding lug, 6, I forma cam surface as at 12. The lid, B, has the usual upstanding portions,1313, each having an aperture for the passage of the retaining bolt. Onthe inner face of one of the upstanding portions, 13, I provide a camsurface as at 1% for coiiperation with cam, 12, upon the journal boxlug. Upon the interior of the lid and adapted to fit closely within theopening in the journal box, I provide a flange, 15, and a flange, 16, isadapted to fit outside of the opening in the journal box. A bolt orrivet, 17, holds the lid and parts in operative connection to thejournal box lug.

The parts are assembled as follows: The spring, 10, is placed in theopening, 8, and is followed by the ring, 11. The lid is then forcedthereon, the part next to the ring being first placed and the springcompressed, the lid meanwhile being held in a vertical position to apoint where the cam openings are co-incident. After the lid is locatedthe rivet, 17, is placed and headed and lid swung into closed position.

In operation, upon lifting the lid, the cams force the lid sidewise,compressing the spring, 10. As the lifting motion is continued, the camsurfaces will ride upon flat portions in order that the lid may besustained at any desired location. Upon returning the lid toward theclosed position the spring behind the cam will return the lid sharply toits position over the journal box opening.

To adapt any M. O. B. lid to this journal box, it would be necessaryonly to remove the spring, then return the ring 11 to the opening, 9,the aperture of the ring for the passage of fastening bolt being of thestandard size.

To prevent spilling of the oil upon movement of the box in service, Iprovide a ledge, 18, standing out from the opening in the inside of thebox.

It will be noted that inasmuch as the bolt fits tightly in the opening,7 and as the part, 11, fits closely within the opening, 9, that thespring is completely protected from the elements at all times.

As various modifications of my invention will readily suggest themselvesto one skilled in the art, I do not confine my invention to the specificconstructions herein shown and described.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. A journal box provided with an upstanding lug having a cam surfaceand an aperture therethrough of varying transverse dimensions, a springwithin said aperture, a follower, in combination with a lid having a camsurface adapted to cooperate with the cam surface of said box lug, apivot rod or pintle extended through the aperture of said box lug, andon which said lid is adapted to turn, said spring bearing at one endagainst the shoulder of said aperture at the junction of portions ofdifferent dimensions and also against the follower to press the sameagainst the lid and maintain said cam surfaces in operative engagement.

2. A journal box provided with an upstanding lug having a cam surface atone end and an aperture therethrough of varying dimensions, a springwithin said aperture, a follower in said aperture at the end of the lugremote from said cam surface, in combination with the lid having a pairof lugs, one of which has a cam surface cooperating with the cam surfaceof the box lug, and a pivot rod or pintle extended through the apertureof said box lug and apertures of said lid lugs, and on which said lid isadapted to turn, said spring bearing at one end against the shoulder ofsaid box lug aperture at the junction of portions of differentdimensions and also against the follower to press the same against thelid lug not supplied with the cam whereby to maintain said cam surfacesin operative engagement.

In testimony whereof, I have hereunto set my hand this 17 day of July,1908, in the presence of two subscribing witnesses.
